"SPINNING AND THE LIKE.

Application filed April ,28, 1921. Serial No. 465,236.

Toall whom it may concern:

Be it known that I, JOHN, P. GAREY, a citizen of the United States,residing at Elmira Heights, county of Chemung, and 5 State of New York,have, invented certain new and useful Improvements in Spinning Framesand the like. 2

My invention ,relates to spinning frames and the like and the objectthereof is to provide simple and efiicient means for stopping thefeeding of rovings through the drawing rolls after, the thread or yarnhas been broken. The main object of in'y invention is to provide simpleand reliable means for said purpose, the advantages in the constructionand mode of operation of which will be apparent from the descriptionhereinafter given.

In the drawings Fig. 1 is a vertical section through a portion of thespinning frame embodying my invention; Fig. 2a plan view thereof; Fig. 3anelevation on a larger scale illustrating my stop means and showing aportion thereof broken away; Fig. t an enlarged view of certain partsshown in Fig. 1; Fig. 5 a section on the line 5-5 of Fig. 3 and Fig. 6 adetailed view of a portion of a stop block and its operating arm. Thespinning frame may be and is shown as of 30 the ordinary type andcomprising suitable frame members including a board or table 10 on whichare arranged a large number of spinning units in the usual manner. Thespinning mechanism proper includes a spindle 11 rotated suitablemechanism (not shown) on which is mounted a spool 12 to receive thethread or yarnpa ring board 13 constructed and arranged to bereciprocated vertically in order to carry the ring 14 and traveler 15thereonlongitudinally of the spool during the winding operation.

The usual drawing rolls are employed, the same comprising three pairs ofrolls 16, 17 and 18 revolved at progressively increasing speeds so thatthe rovings are drawn or lengthened bythe relative movement of thefibres between successive pairs of rolls. A scavenger roll 19 is alsoemployed to cooperate with the rolls 18. Supply bobbins 20, of whichthere are one or more for each set of drawing rolls, are mounted behindthese rolls in position to feed the rovings thereon to the bite of therolls.

The rovings -21 and '22 from the supply "bobbins Y are carried through atrumpet guide 23 to the-first :pair oft-drawing rolls 16,

thence through the, rolls 17 and 18 to the eye or, guide 24- which isarranged in the axis of rotation of the spindle 11 and from which thethread is carried through the traveler15 and thence to the spool 12'.The guide 23 is mounted upon the usual reciprocating slide bar 25 whichextends longitudinally of the frame and is common to all of the sets ofdraw ng rolls, such slide being reciprocated by suitable mechanism, notshown.

The. horizontal bar 26 performs its usual functions of supporting thebearings of the drawing rolls. y

Except forthe specific form and mounting of the guide 2 1 hereinafterdescribed in detail, the mechanism as thus far set forth is that whichis common to most spinning .ma-

chinery and therefore need not be further described.

Referrlng to my stop mechanisimthe same comprises means for gripping therovings after one or more of them or the thread or yarn has been broken,which mechanismis operated by controlling means whose action isdependent upon the continuity of the thread in such guide.

My stop mechanism is located between the bobbins and the drawing rollsand is supported by the bar 26. i

As herein shown the stop mechanism comprises a block 27 which has arecess 28 whereby such block is fitted over the bar 26 and removably andadjustably secured thereto in suitable manner as by means of these;screw 29 passing through one side of the block and bearing against thebar 26. A plate 30 is secured to the block insuitable manner as by meansof the screw 81, such separate construction being preferred although theblock and plate Inightbe made integral. This plate terminates atitsupper I end in a rearwardly eXtending'flang-e 32 which acts as aprotective covering. A flat bar or plate 33 extendsparallel to the plate30 and s attached thereto by THGSHS of the screw 31 and pins passingthrough the two plates. This plate 33 is providedwith guides 35 for therovings, two suchguides' icet on 1'. )a'einas 1 11s tie being piov l ltl is l t nu cl '1 1 stop means being descrlbed is capable of accommodat ng two spinning units.

Between the two plates 30 and'33 and on i v gripped in said opening 38and against the inner side of the plate 33, thereby preventinganyfurther drawing of the yarn from the bobbins. The movement of the stopblock 36 is limited in both extreme positions by the stop pin 39 whichwill bear against the top edge of the plate 33.

These blocks 36 are controlled in their operation by certain trigger,mechanism dependent upon the position of theguide 24,

which is in turn dependent upon'the contlnuity-of the thread or yarn.Referring to t-he controlling means, the same carries at its forward endthe guide Qatand at its rearward upward end a device'cooperating withthe lower endof an arm 40 which is pivoted at its upper end in a slot i1in the lower end of the stop block, there being of course two of thesearms 40, one for each block" of the structure above described. EacharmiO is preferably of the construction shown, particularly with respectto the provision of a shoulder 42 thereon cooperating with the pin 43for imparting to the block 36 its movement in one direction. Each armcarries at its lower end an adjustable trigger 4L4 terminating in acurved trigger proper indicated atferi) whose angularity is adjustablewith respect to its arm 44: and which latter arm is itself ad-; justableby reason of being attached to'the arm to by the screw 46, as detailedin Figs.

3 and 5. r 7

Referring to the details of the controlling means, the guide 24; isadjustably connected by the sleeve 47 and set screws 48 to arod 49 whichis pivotally connected at 50 in a bracket or support 51* mounted on thetable 10. .This rod 49 carries at its rearward enda weight 52 adjustablysecured thereon'an'd such rod also passes through and is secured to ahorizontal cylinder 53 whichin turn is provided with a vertical rod 5ecarrying acylinder The cylinder 55 is provided at its upper end with a;rod 56 curred at its upper end and adapted to cooperate withthe triggere5.

When the parts are in the normal position showniin Fig. l the stopblocks 36 are in their normal. position such as illustrated ;by the lefthand one in Fig. 3 at which time such blocks are 'overbalanced inwardlyand stopped in such position by contact of pin '39 with plate 33.However, iftheyarn or roving,

thread should break or the normal. and

means areadjusted so as to be in substantial balance or in equilibriumor preferably slightly overbalanced 'backwardly so that when the tensionhas released from the guide as the latter will move upwardly as stated.As a result the rod 56 will contact the triggereiS and move the sameinwardly thereby swinging its stop block 36 downwardly to a positionwhere the same will be overbalanced whereupon such block will dropinstantly and rapidly upon the yarn passing through the guide 35 therebyclamping the roving in the manner as hereinhefore described. -The pullof the drawing rolls will then break the fibre of the roving and feedfrom the roving bobbins ceases so thatthere can beno injuriousaccumulation of roving on the drawing or scavenger rolls. The operatorthereupon restoresthe stop block to normal position and rethreads theunit.
